Solution

The correct option is C Trinomial
We are given with an algebraic expression 2p(3p+4q)5q(6p7q)

Step 1:––––––

Simplifying the first product in the expression 2p(3p+4q)5q(6p7q)

2p(3p+4q)=(2p×3p)+(2p×4q)

=6p1+1+8pq (am×an=am+n)

=6p2+8pq

The product 2p(3p+4q) is equal to 6p2+8pq.

Step 2:––––––

Simplifying the second term in the product 2p(3p+4q)5q(6p7q)

5q(6p7q)=(5q×6p)(5q×7q)

=30qp35q1+1 (am×an=am+n)
=30qp35q2
=30pq35q2 ( multiplication is commutative, i.e., p×q=q×p)

The product 5q(6p7q) is equal to 30pq35q2

Step 3:––––––

Now, putting the first and second terms in the product:
2p(3p+4q)5q(6p7q)
=(6p2+8pq)(30pq35q2)
=6p2+8pq30pq+35q2

=6p2+8pq30pq––––––––––+35q2 (Since 8pq and 30pq are like terms.)

=6p222pq+35q2

The product 2p(3p+4q)5q(6p7q) is equal to 6p222pq+35q2.

As the simplified form of the product contains 3 terms in it, it is a trinomial––––––––––.

Therefore, option (c.) is the correct answer.
